Software updates on Wednesday January 12, 2011

The departmental servers coxeter, sphere, and the mail, web, and blog/wiki servers will have a few software updates applied today (Wednesday) afternoon (January 12, 2011) which will require rebooting. Since some updates will be applied while the servers are still up there may be some temporary issues with some software. We hope that any such issues will be minor and by doing most of the upgrading without bringing systems down the shorter downtime will be worth the potential minor problems. Please restart any programs if you observe problems during the upgrades (and please let us know at requests@math.toronto.edu, so we can investigate). We expect the systems to be back to be back up by 5pm.
